Unveiled earlier this month, the 1,800-square foot Go store opened in Seattle only to Amazon employees. The new store eliminates checkout lines by allowing shoppers to enter the store using a new mobile app. Customers can peruse aisles that offer prepared meals such as breakfast, lunch, dinner, and snacks, as well as grocery staples such as baked goods, bread, cheese, and milk.

Shoppers can pick from artisanal foods, too, Amazon Meal Kits, the e-retailer's epicurean challenge to Blue Apron. The meal kits include all the ingredients for a two-person meal that requires about 30 minutes of prep and cook time.

Amazon Go uses computer vision and sensors to detect the items you’re stashing in your virtual cart. First, you scan the new app when you enter the shop. Then, you do your shopping as you usually do. Store sensors throughout the store recognize your cart items and charge them to your account as you leave the shop.

The concept employs the same types of technologies used in self-driving cars: computer vision, sensor fusion, and deep learning, according to Amazon.

"Amazon could analyze items you may have noticed or were potentially interested in buying (i.e., picking something up off a shelf and putting it back down.)," he writes." Combine this with your Amazon.com browsing activities and the company could gear up to serve even more recommended products wherever you’re online."

Like Santa Claus, Amazon could potentially know what you want for Christmas, or at any other time of the year.
